I suppose this is more just a general question, and obviously getting back with every question on an already released game isn't really feasible, but if you're at 54 Hearts by the School Graduation, are you on point?
...I also wound up having no idea how to get some of the Hearts[1], but hopefully that's fine. If you found everything in one playthrough, well...
[1] For instance, it felt like I made the right choices with both Glenda and RJ at graduation, but I didn't get Hearts from either of them, so... I dunno?
